STATES HUGH L. MGAVOY, OFVBALTIMORE, ASSIGNOR OF THREE-FOURTHS OF HISRIGHT TO JAMES FRYER, OF BALTIMORE COUNTY, MARYLAND.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 231,075, dated August10, 1880.

Application filed March 17, 1880. (No model.)

To all whom it may concern Be it known that I, HUGH L. MoAvoY, of thecity of Baltimore and State of Maryland, have invented a new and usefulImprovement in Vapor-Burners, of which the following is a a verticalsection of all parts of the burner eX- cept the tube. Fig. 2 is a frontview of the burner. Fig. 3 is a side or transverse view of I5 same. Fig.el is a top view. Fig. 5 isa vertical section of the burner-tube. Fig. 6is a perspective of the adjustable sleeve for regulating the supply otair. Fig. 7 is a cross-sec` tion through the dotted line in Fig. l. zoThe letter A designates the oil-supply pipe; a, the passage leading tothe needle-valve b. The casin g ofthe passage constitutes the heater a2,and is bored out by a tool entering at the points now shown closed bythe screw-plugs c. d is the receptacle for the oil, which is burned atfirst to heatlup the parts to get it in condition to generate vapor.

` E designates a burner-tube holder, open at both ends, and F theburnertube, provided 3o with a flange, e, which rests on the top edge ofthe tube-holder and serves to support the burner, the tube of whichdepends withiuthe holder. The upper part of the burner-tube immediatelybelow the flange e has an enlarge- 3 5 ment,f, which is adapted to iitsnugly within the holder, and the lower end of this tube is likewiseadapted, by means of an enlargement, j", to fit the tubeholder, and theexterior ot' the burner-tube betweenthe two enlargements 4o is so muchsmaller than the casing of the holder that an annular space, g, isformed therein. (See Fig. l.) An opening, h, is provided in the smallpart ofthe burner-tube communicating from the vapor-passage i, extendingthrough it, and a screw, le, is provided, which enters the passage t'and serves t0 lessen its capacity for the tlow of vapor. The opening inthe lower end of the burner-tube is tlaring or funnel-shaped, as shownat n, Fig. 5, 5o and is immediately over the needle-valve or vapor-exitb', so that the vapor issuing there. from enters the passage t' ot' theburner-tube and carries with it an amount ot' atmospheric air,as will bereadily understood. The amount of air which is thus intermingled withthe vapor may be lessened by means of the adjustable sleeve I, whichtits and is adapted to slide on the lower part, a', of the heater. B yraising this sleeve the space ,separating the vapor-exit b and theflaring opening n, is partly closed, 6o

and thereby the supply of air which can enter the opening u is lessened.As the sleeve incloses that part ot' the heater below the vaporexit, itserves to protect said part from the cooling action ot' the air, andthereby prevents 65 condensation ot' the vapor in its passage throughit.

A hole, p, is on each side ot' the casing ofthe burner-tube holder',(see Figs. l and 7,) and through these holes vapor may escape from the7o annular chambery, to produce a jet which will play on the side of theheater a2. Each side of the holder is provided with a wing, q, curvedbackward toward the heater to partly surround a hole, p, and serves toshield the heating-jet. A slot, u, is formed in the shield,through whichthejet or llame may be seen from the front side.

By this construction the heat to maintain the generation of the vapor isapplied below the burner F, and as the llame issuing therefrom 8o doesnot come in contact with any heating device the light is in no wayinterfered with.

lt will be observed that the burner has a central slot, s, of depthsuiiicient to permit the flame to issue laterally, and on each side ofsaid slot is another slot, t, oi' much less depth. These side slotsincrease the density of the tiame at the upper and central part, thethree slots producing a larger flame.

Having described my invention, I claim and 9o desire to secure byLetters Patent ot the United Statesl. In a vapor-burner, the combinationofthe burner-tube holder E and the detachable burner-tube provided withailange, c, to rest on the top edge of the holder, and having just belowthe flange and at its lower end an enlargement, each of size to itsnugly within the holder and form between the enlargements an annularspace, g, as set forth. roo

2. In combination with the Vert-ical heaterease a?, the tubularburner-tube holder E, having holes p for ythe heating-jet, and theshielding-Wings q, attached to the holder and curved backward to partlysurround the holes7 as set forth.

3. 1n a Vapor-burner, the combination of the holder-ease E, having holesl) for the heatingjet, and a burner-tube Within the ease arranged to litsnugly at its upper and lower ends and form an annular space, g, andhaving an openin g, h, communicate from the vapor-passage fe'- Withinthe tube to the space g, as set forth.
